FAQ
Hi,

Is there a list of configuration parameters that can be set per job.
Specifically, can one set:

- mapred.tasktracker.map.tasks.maximum
- mapred.tasktracker.reduce.tasks.maximum
- mapred.map.multithreadedrunner.threads
- mapred.child.java.opts
- mapred.task.timeout

Also, I am trying to migrate from 0.18.3 to 0.20.2. In the new API JobConf
is deprecated. How does one set the per job configuration parameters that
were available in JobConf (e.g. mapred.map.max.attempts, etc.).

I guess there must be documentation on this but I could not find it. I
appreciate any advice you may have.

Cheers,
Dev
